NUT-LOCK.

SPECIFICATION forming part of Letters Patent 1\To. 605,861, dated June21, 1898.

' Application filed May 25, 1897. erial No. 688,031. (No model.)

To all whom it may concern:

man, in the county of Cook and State of Illinois, have invented certainnew and useful Improvements in Nut-Locks and I do hereby declare thefollowing to be afull, clear, and exact description of the inventiomsuchas will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to certain new and useful improvements innut-locks of that class comprising a locking-bar and a supplementallocking member carried thereby; and it has for its object to provide animproved and simplified construction of this character that can bereadily applied and positive and reliable in its action.

Other objects and advantages of the invention will hereinafterappear,and the novel features thereof will be specifically defined bythe appended claims.

The novelty resides in the peculiar combinations and the construction,arrangement, and adaptation of parts, all as more fullyhere inafterdescribed, shown in the drawings, and then particularly pointed out inthe claims.

The invention is clearly illustrated in the accompanying drawings,which, with the numerals of reference marked thereon, form a part ofthis specification, and in which Figure 1 is a side elevation showingtwo of the locking devices in position, the nuts with which one of saiddevices cooperates being omitted for the sake of clearness. Fig. 2 isavertical cross-section on the line a .t of Fig. 1. Fig. 3 is a verticalcross-section on the line y 'y of Fig. 1'. Fig. 4 is a detail of thesupplemental locking member detached.

Like numerals of reference indicate like parts in the different views.

Referring now to the details of the drawings by reference-numerals, 1indicates the rails of ordinary construction, and 1 the fishplates.

2 is the locking-bar, having the central enlargement 2, as seen in Fig.1 at the right.

3 are nuts on the ends of the bolts 3, that pass through the rail andfish-plates, as seen in Fig. 2.

5 is a bolt that passes through an opening 4. in the enlargement of thebar 2, as seen in Fig. 1 at the right, and receiving a nut 6, as seen atthe left in said figure. This bolt passes through the fish-plates andrail.'

7 is the supplemental looking member. It is formed at one end with thevertical enlargement 8, havingvthe vertical rectangular slot 9, throughwhich passes the bolt 10, screwed into the bar 2, and havingarectangular shank engaging the side walls of said slot. At the other endthis member 7 is formed upon its lower edge with a notch orcut-awayportion 11 to engage over the nut 6, as seen at the left of Fig. 1.

12 are retaining-blocks, each having upon its lower edge or face a notchor out-away portion 13 to engage over the nuts 3, as seen at the left ofFig. 1. Each of theseblocks has a passage or aperture 14 therethrough toreceive the end of the locking-bar 2, upon which they are slidinglymounted.

Vith the partsconstructed and arranged substantially as above set forththe operation is as follows: One of the blocks 12 is fitted over one ofthe end nuts 3. The end of the locking-bar 2 is then moved aconsiderable distance endwise, when the other block 12 is placed overthe other end nut 3 and the locking-bar then brought back to its normalposition and is secured in position by the bolt 5 and nut 6. Thesupplemental locking member 7 is then slid downward so that its notch 11will engage over the nut 6 to lock the same in position, the slot 9 andbolt 10 permitting of such movement.

What is claimed as new is 1. A nut-lock consisting of a locking-bar,retaining-blocks adj ustably mounted thereon one near each end and eachhaving its lower edge cut away to receive a nut, and a supplementallocking member mounted on the locking-bar near its center with anut-receiving' notch upon its under side, substantially as described.

2. A nut-lock consisting of a locking-bar, retaining-blocks adj ustablymounted thereon one near each end and each having its lower edge cutaway to engage over a nut, anda supplemental locking member mounted onthe locking-bar between its ends and formed upon its under face with anotch to engage a nut and having a-vertical slot at its other end to ireceive a rectangular shank of a bolt held in the locking-bar,substantially as and for the purpose specified.

3. The combination With the rails and fishplates, of a locking barhaving a central enlargement, retaining blocks adjustably mounted on theends of said bar and having notches on their lower edges to engage nutson the bolts that secure the fish-plates to the rails, the bolt passedthrough the enlargement of the locking-bar, a nut on said bolt, thesupplemental locking member having upon its under face a notch to engagethe said bolt and provided at the other end with a vertical slot, and abolt held in the locking-bar and I 5 having a rectangular shank engagingin said slot, all substantially as and for the purpose specified.

In testimony whereof I have signed this specification in the presence oftwo subscrib- 2o ing witnesses.
